On charge, the counter-voltage or overvoltage of the battery could be so high as to restrict the charging characteristics at low temperatures.
充电时，蓄电池的反电压或过电压太高，以致限制了低温充电性能。
Pulse signal of proportional amplifier is sent to counter after reduced noise by window voltage comparer.
经比例放大器放大后的脉冲信号经窗口电压比较放大器消除干扰给计数器。
In this method the main part of the pulse width is measured by counter, and the odd of the pulse width is measured by time-voltage conversion method.
该方法以计数器法测取脉冲的主体宽度，用时间-电压转换法测取脉冲的零头时间，并以此作为量化误差的校正值。
